A question regarding sessionisation, being operated in conjunction
between the cookies _utmb and _utmc.
Pretty clear is one direction: user visits a page, both cookies are
set, visitor leaves page and comes back in less than 30 minutes => new
session is started, as _utmc is missing (although _utmb is still up).
What happens "in the other direction": user visits a page, takes a
look and then pauses the site longer than 30 minutes, then he comes
back and continues his visit (loading other pages on the site, etc.).
As I understand, GA notes that the previous session is terminated (no
_utmb). But still _utmc is up. My question: does in this case GA start
a new session or continues the previous one?
If either the __utmb or __utmc cookie is missing a new session is
started. The __utmb cookie expires after 30 minutes of inactivity, so
if they don't view any pages for 30 minutes a new session is started.
The __utmc cookie on the other hand is a "session" cookie in the old
fashioned sense, because it has no expiration, but is deleted by the
browser when the browser is closed.
